Real-world MPG figures revealed for Citroen, Peugeot and DS Automobiles

Models have been tested and independently verified to increase consumer confidence after VW emissions scandal.

A total of 30 models from the French group, which includes Citroen, Peugeot and DS Automobiles, have now been tested with the 27 results announced today (7 July), joining the initial three from March earlier this year.

Results from a total of 14 Peugeot, 11 Citroen, and three DS models have been published in this round of testing, with a number of the most popular variants included.

In November 2015 the PSA Group announced that it would test its cars with Portable Emissions Measurement Systems (PEMS), on a driving cycle carried out on public roads in real-world conditions.

The move is to give buyers fuel economy results that are actually achievable, as opposed to those recorded in laboratory conditions.

The PSA group tests use the same sort of equipment as will be mandatory when new regulations come in over the next few years as Europe makes Real-Driving Emissions (RDE) testing mandatory as part of the vehicle certification process. The procedure and route have been devised in collaboration with two non-governmental organisations - Transport & Environment, and France Nature Environment - and audited by Bureau Veritas, to ensure the results are reliable, reproducible, and reputable.

The measurements were carried out on public roads around Paris, with a balance of different routes - 25 km urban, 39 km rural, and 31 km motorway. Normal driving conditions were used, and passengers and luggage added, along with the use of air-conditioning systems, and routes that didn't avoid awkward climbs.

Gilles Le Borgne, Executive Vice President, Research & Development, PSA Group, said: "The PSA Group has today published real-world consumption data for 30 Peugeot, Citroën and DS models, in line with the commitment to transparency made in October 2015.

"As part of its drive to continuously provide customers with more information, the Group will publish figures for another 20 models by the end of the year and introduce a simulator allowing customers to reduce their fuel consumption depending on driving conditions, thereby lowering their CO2 emissions.

"In 2017, the PSA Group will move to the next level by extending measurements to pollutant emissions of nitrogen oxides (NOx) in customer driving conditions."

Greg Archer, Clean Vehicles Director at Transport & Environment, said: "This real-word test provides more representative information to consumers than new laboratory tests, helping them to choose the most fuel-efficient, low-carbon models."
